/sci/ - Science & Math

<div class="math">\int_0^{2 \pi} [f'(x)]^2 dx \ge \int_0^{2\pi} f(x)^2 dx</div>

Where <span class="math">f(x)[/spoiler] is <span class="math">2\pi [/spoiler]-periodic and <span class="math">int_0^{2\pi} f(x) = 0[/spoiler].

I remember when this board wasn't infected by trolls

we used to talk about the absurdity of life and death and the vastness of the universe

we used to have fun :{

now you troll each other and make this place unbearable

where did we go wrong /sci/? where did we falter

i can't upload a 14mb picture, so have this instead.
